u_" must be understood
at the very start of your self-development. All your plans for the
growth of the characteristics you need to assure your success should be
based on comprehension of your _duality_. The two "You's" in yourself
not only are distinctly _different_, but they are also very intimately
_related_ in all their functions. Neither your "ego" nor your body is
independent of the other part of your duality. So, of course, both must
co-operate fully in every _process_ of your self-development; and your
_training methods_ should be planned for the bettered growth of your
inner and outer man _as a team_.

[Sidenote: Team-work Processes]

You understand now that your growth should be on a dual basis; that you
have two different men to develop, not just one; and that they must be
handled _discriminatively_, but _together_.

Next it is necessary that you know in _exactly what ways_ the activities
of the mind man, or ego, are related to the activities of his body, or
the physical man. Otherwise you cannot comprehend the team-work
processes by which any desired qualities of manhood can be developed
from their rudiments. Perhaps the reason you have not yet succeeded
fully is that you have been a "one-horse" man and have not trained your
dual self to be an effective _mind-and-body_ team pulling together. It
takes both mind and body to bring to market successfully all the "best
capability" of a man.

[Sidenote: Training Methods]

Evidently, as a pre-requisite to self-development, one should have
knowledge of the particular processes that result _surely_ in natural,
easy, rapid growth. Otherwise he would be more than likely to employ a
wrong or only partly right _method of training_. So as a student of
yourself you need to start with comprehension of your two _bases_ of
development, mind and body. It is necessary next that you acquire
scientific knowledge of the distinct but related _processes_ of
developing your two selves severally to work together as a team. Then
you must learn the particular _methods_ of cooeperative mental and
physical training that are most effective in accomplishing the man
growth you desire.

[Sidenote: Neither Mind Nor Body A Unit]

Not only have you two selves, but neither "You" is a _single unit_. Your
mind, as well as your body, is made up of distinctly different but very
intimately related and associated _parts_. Your "mind" cannot be
developed as a _whole_. Its parts must be severall
